' of the wall of said ribs serve as bases for BUILDING swan-E.

stones or blocks, which will save building material, reduce the time of laying the stones and facilitate the handling thereof.

Fig. 5 a cross section-of a part of a wall built from my new stones; Fig- 6 a topplan view of a new binding, stone; Fig. 7 an end vlew thereof; Flgs. 8 and 9' perspective views thereof; Fig. 1-0, a top plan view of a part of a wall made up. of stones shown in Figs. 1-5 and the binding stonesshown in Figs- 6.9; Fig...l1 a cross section of said wall and Fig; 1a.; similar view showing two superposed rows of such building stones.

The main stone A comprises a top a, one side wall 6, two outer or end ribs or slats 0 and two inner or intermediate ribs or slats (1. These ribs are all of uniform thickness and project at right angles to the top and side wall and are made flaring as at 0' and (1 toward their bottom, so that their outer side edges project laterally in an incline from underneath the top a. The lower edges the blocks. The space between the two central or intermediate ribs is substantially equal to the double thicknessof a rib. The block or stone. thus produced is hollow and open at its bottom and at one of its sides.

When constructing a wall, the stones are placed in parallel rows with the open sides I) of the stones of the opposite rows facing in a displaced position one another, so that the adjoining end ribs 0 of adjacent stones of one row are opposite and project into'the space between the intermediate ribs d of a stone in the o osite st ne ro w e y he "ing like those of the ribsc, d1

opposite rows of stones becomeinterlocked" with one another. The stones of the-two r() ws[are arranged contiguouslyas at c (Fig. For a thicker wall, I use in additionto the two rows of stones A a binding stone B. The later, like the main'stone A comprises a topf, a longitudinally extending vertical I cefiitral wall g, end ribs 7 and intermediate r1 s l p uniform with one another and substantially vequal to'the thickness of a'ri'b'ofthe stone These ribs z" and j," in thicknessare A and extend at each side o f the central wall 9 also at right anglesthereto and tosaid top and their outer'sideedges'i j arefi'ar- In use, themain stones areplaced in paral- Y lel rows and in alignment" withand-h faei ng "one another with their open sides 6 butdis placed transversely a distance -equal to the width thereof or that of a binding stone. The binding stones are inserted between the opposite mainstones A placed end wi'se in such aposi-tion'relative to' themai n stones A that/the adjoining endlribs of each two adjacent: binding stones B engage tl ie space between the central ribs of the two rows of of main stones A and the two end ribs ices between the adjacent stones are not con-- tinuous and the factthat the mortar, when I the stones are pressed into position, is forced upwardly along the wall and ribs sealing the horizontal crevices, the passage of air through the wall is rendered'imposslble.

The trapezoid-shaped ribs not only in sure the stability of the stones and serve as reinforcements, but also eflectively distribute the load, since every upper main stone transmits the load to two lower stones and every upper binding stone to three lower stones (Fig. 12).

The stones should preferably beso dimensioned that in every direction it a multiple of the standard size of an ordinary brick.

This enables the use of said stones between bricks and thefillingout of empty corner spaces. g
